Line Lock option flashing on and off

[olive360]

Has anyone heard of this problem before? The option to open up Line Lock is flashing on and off, but not in any predictable pattern. It's like something has a short because it will actually let me highlight it when it's on, but I'm not able to hit ok fast enough before it blacks out and resets the selector to the top.

I tried pulling up and down on the handbrake incase it was just slightly on. I tried turning on and off the car and it didn't fix it either. Tried in first gear and in neutral.

Really hope I don't have to take it in to the dealer. Last time I did that, the skeevy looking guy made too many "I'm gonna rip some sweet burnouts in this thing" jokes that made me feel like it was the truth. Plus half of my gas was gone for a light switch replace..........

Only automatics have linelock..

whoa whoa, are you sure? I have always had linelock as an option. I've never used it. but it's always been there ready to go. I'll upload a video of what I'm talking about. It even lets me select it a few times before it boots me out.

 

[boosted4life]

Yes I've thought the same when I bought my car. It's there but does not work with manual cars. We have launch control.

 

[olive360]

well why would it be flashing like that?

Actually I may be wrong I pulled up a couple vids on you tube with Manuals and they can do it. Now I'd like to know as well.

 

[IvanCRF]

Yes, manuals do indeed have line lock. All GTs will have line lock.

I'm trying to add the video now. but I'm talkabout the actual link to open link lock. where it says "Line Lock" in track apps is flashing and won't let me open it. trying to upload to youtube now.

I really wonder if whatever detects if my foot is on the break is going out. that's how it's behaving.

Ok here's the video. What to look for: notice it is flashing at the start of the video. that's what it's doing. also notice about 3 times it lets me quickly select it. Also note that while the parking break is on during parts of the video, it's doing the same thing with it off. Note that it has never done this before and every time I've checked it's been a lit up option.

My Line Lock was "grayed out" as in your video when I was on an incline such as a driveway.

From page 145 of the owner's manual:


Line Lock (If Equipped)
Line Lock is a feature intended for use at
tracks only and should not be used on
public roadways. Use of this feature will
result in significantly increased rear tire
wear. It is intended to condition the rear
tires to maximum traction prior to track
use. Line Lock maintains brake force at the
front wheels, allowing the rear wheels to
spin with minimal vehicle movement.
This feature is located in the Track Apps
menu. Make selections through the 5-way
information display control and OK button
located on the steering wheel.
Using Line Lock
There are three Line Lock stages:
• Initiated.
• Engaged.
• Off.


Initiating Line Lock
The initiation stage verifies that the vehicle
is ready for Line Lock function, and
confirms driver intent. Follow the prompts
in the information display in to initiate Line
Lock.
The following conditions must be met to
initialize Line Lock:
• The vehicle is on a level surface.
• The engine is running.
• The vehicle is traveling less than 25
mph (40 km/h).
• Selectable Drive Mode is not in wet
mode (if equipped).
• There are no AdvanceTrac faults.
If you want to cancel Line Lock once it is
initialized, press the left information
display control. Once initiated, Line Lock
is prepared for activation and will remain
initiated up to 25 mph (40 km/h). If vehicle
speed exceeds 25 mph (40 km/h), Line
Lock will be automatically canceled.
Engaging Line Lock
Follow the prompts in the information
display to engage Line Lock after it is
initialized. To engage, firmly apply the
brakes. Then press the OK button. Once
engaged, release the brake pedal. The
front brakes will remain applied and the
rear brakes will release. At this point, the
engagement timer is initiated and shown
on the driver information display.
The following conditions must be met to
engage Line Lock:
• The vehicle is on a level surface.
• The engine is running.
• The vehicle is stopped.
• The parking brake is not applied.
• The driver door is closed.
• The transmission is in a forward gear.

Mustang (), enUSA, First Printing
Stability Control
• Selectable Drive Mode is not in wet
mode (if equipped).
• There are no AdvanceTrac faults.
• The steering wheel must be in the
straight ahead position.
Releasing Line Lock
While Line Lock is engaged, you can exit
(release) the feature using the OK button.
When you press the OK button, Line Lock
releases immediately and normal vehicle
function will resume. When Line Lock is
engaged, a countdown timer shows the
remaining time before Line Lock is released
automatically. If you exceed the time limit,
or another vehicle condition requires Line
Lock to release, the system will safely
disengage and normal vehicle function will
resume.
Note: If the brake pedal is applied while
Line Lock is engaged, Line Lock
automatically cancels and normal brake
function resumes.

My line lck option has ever worked. Go through the steps and its tells me there is an issue and to look through my manual. Brought it to the ford dealer and they were lost and didn't even know the car had line lock. I never attempted to fix it after since I never use it.
